If you notice that your scripts take a lot of time to handle specific requests(messages) it might be time for a little profiling. You can use kchachegrind for this.

[edit] Configuration
javascript.conf
[general] allow_trace=yes
[edit] In code
At the start of the main js file add:
#pragma trace "cachegrind.out.filename"
Make sure you don't add this in any of the included files
[edit] Run test in yate
Start Yate, make the test you wanted and then stop Yate. After stopping you will find a file called "cachegrind.out.filename" in the directory where yate was started from.
[edit] Running cachegrind
The command to use kcachegrind:
kcachegrind cachegrind.out.filename
Note! kcachegrind is a GUI so if you are using ssh to connect to that server, disconnect and reconnect with "ssh -X"
